Optical fiber coupler is passive devices which carve up the optical signal from an optical fiber to multiple fiber and widely used in optical transmission systems, telecommunications networks, cable television (CATV), LAN, with fiber optic connectors belong to be by far the largest use among passive components.
Fiber coupler function can be divided into two categories:
(1) By optical power distribution, this coupler is usually called a splitter (Splitter).
(2) By wavelength of light distribution, such couplers are usually referred to as wavelength division multiplexing (WDM)
Optical splitter is a passive devices which can achieve the optical signal shunt, connecting the optical line terminal (OLT) and Optical Network Unit (ONU) devices, is one of the most critical devices which quality performance has a direct influence if the network is reliable and secure. In accordance of if can one light channel be divided into N-way channel of uniform intensity or non-uniform intensity of light channel, by the division of common methods of making, there are melting biconical taper (FBT) optical splitter, Planar Lightwave Circuit (PLC) optical splitter.
Optical wavelength division multiplexing is a device which can put different wavelengths of the two (or more) optical signals together and also separate the two optical signals with optical fibers (wave) (partial wave). Can be divided into a coarse wavelength division multiplexing (CWDM) and Dense Wavelength Division Multiplexing (DWDM).
The Company provide customers with a fused biconical tapered optical splitter, planar waveguide optical splitter and dual-wavelength WDM. No matter what type of products, all with low insertion loss, low PDL, compact design, high return loss, high reliability and stability, are widely used based on all kinds of FTTX PON engineering and cable spread line. The product meets the standards of the YD / T 1117-2001 communications industry, in line with the requirements of the Telcordia GR1209/1221 standard.
